Description

Technical Field

[0001] This utility model relates to the field of natural gas metering, specifically a remote metering device for natural gas used in long-distance pipelines. Background Technology

[0002] Natural gas metering refers to the process of measuring the flow rate and mass of natural gas during its flow. This involves the determination, detection, calculation, transmission, and control of the volume, mass, and energy of natural gas. The unit of measurement for natural gas is usually the standard cubic meter (Nm³). 3 This is a unit of volume for gas under specific conditions (0 degrees Celsius, 1 standard atmosphere). Natural gas metering is crucial for ensuring the accuracy and fairness of energy transactions, as it not only relates to the sale and use of natural gas but also affects energy efficiency and environmental protection. To achieve accurate metering, it is necessary to adopt appropriate metering equipment according to relevant technical specifications and standards, and ensure that the design, construction, operation, and maintenance of the entire metering system are of high quality. To facilitate natural gas metering operations, remote transmission equipment is required. The "Remote Transmission Equipment for Natural Gas Metering in Long-Distance Pipelines" disclosed in application number "CN202221518764.6" is an increasingly mature technology. Its "Utility Model, through the setting of a first airbag, rubber friction layer, ultrasonic flow meter body, sensor, fixing frame, screw sleeve, and hose, can not only block the gap between the inlet and the pipeline, but also further improve the sealing of the inner cavities of the first and second housings, preventing external dust and other impurities from entering through the gaps and affecting the accuracy and service life of the sensor." This design increases the friction of the rubber friction layer on the first airbag, thereby improving the stability of the first and second housings. It eliminates the hassle of limiting the rotation of the extrusion column, further improving installation efficiency. Simultaneously, the ultrasonic flow meter transmits the monitored data to the PLC controller, which then controls the 5G communication module to remotely transmit the data to the client, facilitating data retrieval by staff. This makes it more practical for the use of a "natural gas metering remote transmission device for long-distance pipelines." However, this remote transmission device still has the following drawbacks: While the first housing, second housing, first airbag, and second airbag do achieve a sealing effect, the structure itself has a simple protective effect and is not conducive to enhancing the protective effect while ensuring sealing. Therefore, it is necessary to provide a remote transmission device that can improve the protective effect. Furthermore, existing remote transmission devices are not convenient to connect to gas pipelines, affecting ease of use. Therefore, it is necessary to provide a remote transmission device that is easy to connect to gas pipelines and improves ease of use. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a remote metering device for natural gas in long-distance pipelines, including a protective component 100 and a connecting component 200;

[0025] The protective component 100 includes a remote gas meter 101. A flange 102 is fixedly connected to the side surface of the remote gas meter 101. A damper 103 is hinged to both ends of the flange 102. A first spring 104 is installed on the side surface of the damper 103. A support block 105 is hinged to the lower end of the damper 103. A second spring 106 is installed at the lower end of the remote gas meter 101. A protective shell 107 is sleeved on the side surface of the remote gas meter 101. A sealing plate 108 is connected to both sides of the protective shell 107. A protective plate 109 can be detachably installed on both sides of the protective shell 107. A connecting rod 110 is inserted between the two protective plates 109. Bolts 120 are fixedly connected to both ends of the connecting rod 110. A limit nut 130 is threadedly connected to the side surface of the bolt 120.

[0026] The connecting assembly 200 includes two arc-shaped clamping plates 201 installed at the lower end of the protective shell 107.

The surfaces of the two arc-shaped clamping plates 201 are provided with second screw holes 203, and screws 204 are threaded into the interior of the second screw holes 203.

[0027] In one specific embodiment, the protective component 100, in conjunction with the connecting component 200, not only ensures the sealing of the remote transmission device but also provides shock absorption protection for the remote gas meter 101, thereby enhancing the practicality of the remote transmission device. Furthermore, the combined structure facilitates connection between the remote transmission device and the gas pipeline, improving the ease of use. In use, first, the two arc-shaped clamps 201 are rotated and clamped onto the side surface of the gas pipeline; then, the screws 204 are threaded onto the bottom to connect the two... The arc-shaped clamp 201 is used to fix the housing 107 and the gas pipeline. At the same time, the housing 107 and the two protective plates 109 are sealed by the connecting rod 110, bolt 120, limit nut 130 and sealing plate 108. When the housing 107 is in use, the remote gas meter 101, which is suspended inside the housing 107, vibrates. The damper 103, together with the first spring 104, can play a shock absorption and protection role. At the same time, the buffering effect of the second spring 106 can significantly enhance the practicality of the remote transmission equipment.

[0028] Please see Figures 3-5 The side surface of the flange 102 has two hinge grooves 111. The upper end of the damper 103 is fixedly connected to a hinge shaft 112, which is hinged inside the hinge groove 111.

[0029] In one specific embodiment, the hinge shaft 112 and the hinge groove 111 are hinged to each other, which facilitates the damper 103 and the remote gas meter 101 to be hinged to each other and rotate slightly at an angle, so as to achieve the effect of shock absorption and protection.

[0030] Please see Figures 3-5 The lower end of the remote gas meter 101 is provided with a plug hole 121. The upper and lower ends of the second spring 106 are fixedly connected with plug rods 122, which are inserted into the plug hole 121.

[0031] In one specific embodiment, the insertion rod 122 is inserted into the insertion hole 121, which can improve the ease of disassembly and assembly between the second spring 106 and the remote gas meter 101.

[0032] Please see Figures 3-5 Both sides of the inner wall of the protective shell 107 are fixedly connected with ear blocks 131. The surfaces of the ear blocks 131 and the protective plate 109 are provided with positioning holes 132, and the connecting rod 110 is inserted into the positioning hole 132.

[0033] In one specific embodiment, the connecting rod 110 is inserted into the positioning hole 132 and cooperates with the lug 131 to improve the connection stability between the protective plate 109 and the protective shell 107.

[0034] Please see Figures 3-5Several locking rods 141 are fixedly connected to the opposite surfaces of the two protective plates 109. Several locking holes 142 are opened on both sides of the protective shell 107, and the locking rods 141 are inserted into the inside of the locking holes 142.

[0035] In one specific embodiment, the latch 141 is engaged inside the latch hole 142, which can facilitate the improvement of the installation tightness between the protective plate 109 and the protective shell 107.

[0036] Please see Figures 3-5 Stabilizing blocks 151 are fixedly connected to both sides of the protective shell 107, and stabilizing support rods 202 are inserted into the inside of the stabilizing blocks 151.

[0037] In one specific embodiment, the stabilizing block 151 can work in conjunction with the stabilizing support rod 202 to provide support and improve the connection stability between the arc-shaped clamp 201 and the protective shell 107.

[0038] Please see Figure 6 The upper end of the arc-shaped clamping plate 201 is provided with a stabilizing hole 211, and the lower end of the stabilizing support rod 202 is inserted into the stabilizing hole 211.

[0039] In one specific embodiment, the stabilizing rod 202 is inserted into the stabilizing hole 211 to provide support and improve safety during use.

[0040] Working principle: In use, firstly, the two arc-shaped clamping plates 201 are rotated and clamped on the side surface of the gas pipeline. Then, the screws 204 are threaded to the bottom, thereby fixing the two arc-shaped clamping plates 201. This allows the protective shell 107 to be connected to the gas pipeline. At the same time, the protective shell 107 and the two protective plates 109 are sealed by the connecting rod 110, bolts 120, limit nuts 130, and sealing plates 108. When the protective shell 107 is in use, the remote gas meter 101, which is suspended inside the protective shell 107, vibrates. The damper 103, together with the first spring 104, can play a shock absorption and protection role. At the same time, the buffering effect of the second spring 106 can significantly enhance the practicality of the remote transmission device.
